VISE ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 303,345, dated August12, 1884.

Application filed February 18, 1884. (No model.)

5 9 aZZ whom it may concern:

Be it known that I, WILLIAM VANDERMA N, of Villimantic, in the county ofWindham and State of Connecticut, have invented 'eer tain new and usefulImprovements in Pipe- Vises and I do hereby declare that the followingis a full, clear, and exact description thereof, whereby a personskilled in the art can make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon.

Likelctters in the figures indicate the same parts.

Figure l is aside view of a vise embodying my improvements. Fig. 2 is atop view of the same. Fig. 3 isa face view of one of thejaw-frames,.with .parts in section. Fig. 4 is a view of an alternateform ofjaw. Fig. 5 is a plan view of bending-forms for attachment to thevise. Fig. 6 is an edge view of the same. Fig. 7 is a plan view of myimproved vise with parts of the jaws broken away, and showing the stepsin the method of bending an offset in a pipe.

The object of my invention is to provide for the useof plumbers,gas-fitters, and the like workmen a compact device that shall embody inthe main part of the vise and the attachments thereto necessary toolsfor bending, offsetting, and otherwise working pipes of variousdiameters.

In the accompanying drawings, the lettera denotes a metallic jaw-frame,preferably cast to shape,and having means for attaching it to a bench;b, the movable jaw-frame, having the extension 0, that reciprocates inthe socket in the fixed frame a in the usual manner the frame I) beingoperated by means of the screwspindle I), having a head in which isfitted the usual sliding lever, d, for rotating the spindle. The jaws,as shown in Fig. 1, are provided with flat grasping-faces b a, and justbelow the jaws are the dovetailed sockets adapted to receive and holdthe removable toothed pipe-jaws, which are circular in general verticaloutline of the grasping-faces, and are placed in groups of two or morefixed on each jaw, as shown. These toothed jaws may extend completelyacross the frame from side to side, orare preferably shorter than themam aw, and so arranged as to leave a space, 0, which enables these jawsto grasp a pipe on each side of a coupling when the vise is used to holdpipesjoined by such a device. These jaw's e are reversible andinterchangeable, so that when one part of the circular grasping-fa ce isworn they may be reversed in their sockets,

and so present sharp'instead of worn teeth,

and are also readily replaced by new ones. In theupper surface of thefixed jaw-frame a a circular groove, a, is formed, that is especiallyadapted for use in the straightening of bent pipes. The extension 0 hasbetween the jaws a and b a transverse hole, c',through which a pipe maybe thrust, and on the same horizontal plane with this opening is agroove, 0, in the rear end of theextension, a groove, (t!!! socket c inthe side of the frame.

The letter h denotes a semicircular frame, having a peripheral groove,h, and on the flat edge the projection h of such size as to fit closelywithin the socket a on the frame a. To use this form it is attached tothe frame a by means of the socket and projection, as shown in Fig. 7,the end of a pipe is inserted in the opening a, the movable jaw closeduntil the pipe bears against the groove a, and while the end is heldtightly in. position the pipe may be swept around and bent in the grooveh and a half-bend made. The form j has a projection, also formed to fitthe socket in the frame a, and a grooved face adapted to form aquarter-turn in the pipe by a similar method to that employed in theform h.

In the frame I), and opening laterally, is the hole 1/, on the samelevel with the hole 0, and a clamp-screw, f, projects into this holefrom the front of the vise, and is used to clamp within it a pipe orred. The clamp-screw g,

, in. the front of the fixed frame a, and the that is used to secure thevise to the bench,

from the clampserew, and its threaded end turned into the socket d inlever (1 until the curved end of lever k is so adjusted as to restagainst the front edge of the pipe at any desired distance from the sideof the vise, (see 2, Fig. 7,) and the lever d is then clamped firmly bymeans of screw f. The pipe is then grasped and bent forward into thegroove 70" in the curved part of the lever 70, and the offset finished(see 3, Fig. 7 ,)when the pipe may be released and removed from thevise. The alternate form of removable pipe-jaw shows the upper one ofthe pair (denoted by e in Fig.4) as having both a flat graspingface, 6which forms its upper portion for general use, and the lower partrounded with serrated or toothed grasping-surface that co-operates withthe jaw e, and an opposite and similar set in holding pipes and the likeobjects. This form is especially useful in small sizes of Vises, as itbrings the pipe-grasping portion nearer the upper edge of thejaw-frames, which is desirable where but little space can be got between the top of the screw-spindle and the top of the jaw-frames.

The pipe-grasping part of the jaw a -may be limited to the sides, (seeplan view in Fig. 4,) as in the other form of these jaws.

I claim as my invention- 1. In a vise, the jaw-frames a 1), bearingjawswith transverse dovetailed sockets, in combination with the removablepipe-jaws 6, having the outward-curving toothed orserratedgrasping-faces, and dovetailed tenons fitting the respective mortises,and affording meam! whereby the jaws are secured to the frame, allsubstantially as described.

2. In combination, the jaw-frame a, having the lateral socket a andgroove a, movable jaw 11, with extension 0, having the transversescribed, and jaw-operating mechanism of screw-spindle and lever, thefixed jaw, and the extension-bearing, the opening and grooveco-operatingto grasp a pipe or rod, all snb-- stautially as described.

5. In a vise, in combination, the frame a, with groove a on its uppersurface, a lateral socket, a. and clanipinggroove a, a movable jaw, b,having the extension 0, with opening a, and the interchangeable forms, hand j, all substantially as described.

6. In combination with avise havingasocket, a., the interchangeableforms h and j, with peripheral grooves, substantially as described, andprojections whereby each form is attached to the vise, all substantiallyas described.

7. In combination, the vise-frames a and b, with openings 0 and b andthe levers d and la, with respective sockets and grooved bends, allsubstantially as described.
